' y4 claims. (C1. 3o12l This invention relates to a .type of instrument that is commonly known as a safety razor in which a removable cutting blade is embodied, the invention having reference more particularly to the frame and handle of such a razor required to hold and guidethe cutting blade. l

An object of the invention is to provide an improved razor frame and its handle which shall be of such construction as to enable the frame to lo be instantly adjusted on-the handle so that the handle may-be set at variousangles relatively to the frame` that may be convenient or desired by the user, which shall not be costly to manufacture.

Another object is to provide an improved safety razorl frame which shallV permit the insertion of a razor blade of conventional type in a simple and reliable manner. o e l A further object is to provide an improved safety razor frame in which the blade may be readily shifted by reversal of the blade 'so that diierent` portions of the cutting edge may be brought into proper position for use after other portions may have become dulled by use.

A still further object is to provide means for positively adjusting a safety razor blade in its frame so as to permit relatively closer shaving than normally and without tending to cause the blade to shave uncomfortably close, or dangerously so, and shall not be liable to cause injury to a persons fingers while the razor is being washed after use.

With the above-mentioned and other objects in view, the invention consists in an improved safety razor having novel and improved features including an improved handle connection, and improved frame structure, and vimproved means whereby to adjustably hold a blade in the frame; the invention consisting also further in the-parts and the combinations and arrangements of parts /f as hereinafter particularly described and further dened in the appendedclaims.

Referring to the accompanying'drawing- Figure 1 is a side View of the improved safety razor; Fig. 2 is a side View of the razor with the frame in open positioi'i and the handle turned to a relatively different position, the handle being partially broken away; Fig. 3 is a plan view of aneinverted cup embodied in the handle mounting, being on an enlarged scale; Fig. 4 is an end view of the improved handle, also on an enlarged scale; Fig. 5 is a sectional detail of the improved handle mounting on an enlarged scale with a longitudinal section of the head member of the frame; Fig. 6 is a top plan of the head member of the 'frame and portions thereof,valso on an enlargedk y scale; Fig. 'l is a plan of a common type of a safety razor blade; and Fig. 8 is a plan of a removable faee part of the Ahead `member of the frame, being adapted'for use behind a conven- 60 tional blade when desired.

Similar reference characters in the various iigures of the drawing indicate-corresponding elements or features ofr 'constructionherein referred to in detail. j l

Practically4 embodied the invention has an improved adjustable handle 1 enabling therazorto be most advantageously used in the manner in which'saety'razors generally are usedand manipulated. 'The frame has a head 4member 2 70 having a convexly roundedy face 3, the member being oblong in plan'and having guard fingers 4 projecting from one of the longer edges thereof,y the opposite edge having guardngers 4' on its edge but in relatively staggered arrangement, so that in one row of iingersthe fingers being on parallel transverse lines the fingers of the opposite row'shall be located between such lines. The middle portion of the member has a screw-threaded stud 5 rigidly secured thereto and: projecting 30 from the back or top of themember. -A cup 6 having a center hole 7 is placed over the stud and is seated on the-back of the head member and" supports a coil spring .8 thereon which yieldingly supports an annular cap 9.` Thehandle 1 has a 85 chamfer 10 on one end, so that the end is frustoconical, and a screw hole 11 isdrilled into the handle through the chamfered portion so as to be approximately on an angle of 45 degrees relatively to the longitudinal axis of the handle, permitting the chamfered portion to bear upon the top of the cap 9, against the pressure of the spring 8 which with frictional resistance of the screw threads in the connection tends to hold the handle in the position to which it may be adjusted, and prevents turning of the head member relatively to the handle during use of the razor. One of the shorter end portions o f the head member has a pair of hinge ears 12, 12A'y to which a hinge pin 13 is connected, the opposite shorter end having 100 a catch nger 14 thereon. The body portion of the head member has spaced apart apertures 15 and 15' to `receive positioning devices.

The razor frame has a front' face plate 18 which is oblong in plan and is provided with a hinge ear 17 that is connected with the hinge pin..v 13 so that it may swing to the head member, or away from it toa limited extent and stopped by the ends of the hinge members contacting with adjacent portions of the parts to which the hinge no members are fixed. The opposite end of the face plate is provided with a spring latch 18 which engages with the catch nger 14 to hold the face plate substantially to the head member. The front of the face plate is convex, the back of the plate being concave to conform to the convexity of the face 3 of the head member and is provided with spaced apart posts 19. and 19 that are receivable in the apertures l5 and l5 whereby to guide and hold a suitable razor blade 20 in place adjacent to the guard fingers, the blade having openings 2l, 21 to receive the posts.

The razor is provided With a thin shim 22 that is slightly narrower than the cutting blade and has apertures 23 and 23 to receive the posts and removably hold it in proper position on the blade and in contact with the face 3 of the head member to permit close shaving with safety.

When assembling the parts the frame is opened as indicated in Fig. 2, the blade 20 is placed upon the back of the face plate, the shim placed upon the blade and the frame closed and the hinged parts latched together, so that the blade and the shim become rmly clasped yin proper position as indicated in Fig. l. When not desired the shim may be omitted, as will be understood, the shim being extremely thin so that its absence does not prevent secure clamping of the blade in the frame.

In practical use the razorfis operated to shave as may be desired, the handle being readily turnedy to obtain such adjustability as the user may desire, thus enabling the blade to be moved in the various directions and be handled to be conveniently and firmly held by hand, the adjustable connection of the` handle with the head member of the frame affording convenient handling not only in the use ofthe razor when shaving, but in order to remove or to reverse the blade and in the insertion of another blade.

What is claimed is:

1. A safety razor including a frame and a razor blade secured in the frame, the frame having guard fingers projecting beyond the blade, a cup` and yieldingly supported on the spring,.and a handle having a frusto-comcal end and a screwhole therein receiving the screw and said end shiftably bearing upon the annular cap, the screw-hole being on an angle of inclination relatively to the longitudinal axis of the handle.

2. A safety razor including a frame and a razor blade secured in the frame, the frame having guard ngers projecting beyondv the blade, an annular flat-top bearing cap vyieldingly mounted on the back of the frame, a screw rlxedly secured to the frame and extending through the cap, and a. handle disposed at an acute angle to the frame having a frusto-conical end constituting a continuous inclined face directly turning on the screw and shiftably bearing on the cap.

, 3. A safety razor including a frame and a razor blade removably clamped in the frame, the frame having guard fingers on opposite edges thereof projecting beyond the blade, a cup central on the back of the frame, a coil spring seated in the cup, an annular cap yieldingly supported on the spring, a screw secured to the frame and extending through the cap, and a handle having a beveled bearing portion and a screw-hole therein receiving the screw, the bearing portion shiftably bearing upon the annular cap. l

4. A safety razor including a frame head -member having guard fingers on opposite side edges thereof on different projectional-lines on the different edges respectively, the head member having spaced apertures therein' and a cup on the back of the member intermediate of the aper-l tures, a coil spring seated in the cup, an annular` cap supported on the spring, a screwsecured to the head member and extending through thev cap', a handle having a beveled bearing portion and a. screw-hole therein receiving the screw, the bearing portion shiftably bearing upon the cap, ya frame front plate hinged at one end to one end of the head member andv having' a 'latch at its opposite end, thefront plate having spaced posts receivable in said apertures, anda twoedgereversible razor blade removably arranged on the back of the front plate to co-operate with said fingers, the blade having apertures receiving said posts.
